* cygwin.din: Make clock SIGFE. Add clock_gettime, sigwaitinfo, timer_create, timer_delete, timer_settime. * include/cygwin/version.h: Reflect above additions. * fork.cc (fork_child): Call fixup_timers_after_fork. * signal.cc (sigwait): Remove unused variable. * timer.cc: New file. (clock_gettime): Define new function. (timer_tracker): Define new struct used by timer functions. (timer_tracker::timer_tracker): New function. (to_us): New function. (timer_thread): New function. (timer_tracker::settime): New function. (timer_create): New function. (timer_settime): New function. (timer_delete): New function. (fixup_timers_after_fork): New function. * cygthread.cc: Bump thread count. * signal.cc (sigwaitinfo): Define new function. (sigwait): Redefine based on sigwaitinfo. * include/cygwin/signal.h (sigwaitinfo): Declare. (sigwait): Ditto. * dtable.cc (dtable::vfork_parent_restore): Avoid double close of ctty when ctty == ctty_on_hold. * cygtls.h (_threadinfo::threadkill): New element. (_threadinfo::set_threadkill): Declare new function. (_threadinfo::reset_threadkill): Declare new function. * dcrt0.cc (dcrt0_1): Call here so that it will be possible to attach to running process with #(*& Windows Me/9x. (initial_env): Try to initialize strace if uninitialized. * gendef: Don't zero signal if threadkill is set since that will happen in the called function. * signal.cc (sigwait): Ensure cleanup in error conditions. * sigproc.cc (sig_send): Clear packet mask storage. (wait_subproc): Fill in child exit code in siginfo_t structure. * thread.cc (pthread_kill): Set threadkill flag. * tlsoffsets.h: Regenerate. Throughout, use siginfo_t to fill out all signal information for "kernel" signals. * cygtls.h (_threadinfo::set_siginfo): Declare new function. * cygtls.cc (_threadinfo::set_siginfo): Define new function. * dcrt0.cc (do_exit): Accommodate siginfo_t considerations. * exceptions.cc (handle_exceptions): Ditto. (sig_handle_tty_stop): Ditto. (ctrl_c_handler): Use killsys() to send signal. (sigpacket::process): Rename from sig_handle. Use siginfo_t field from sigpacket for everything. (tty_min::kill_pgrp): Accommodate siginfo_t considerations. (fhandler_termios::bg_check): Ditto. * fhandler_tty.cc (fhandler_tty_slave::ioctl): Use killsys() to send signal. * signal.cc (kill_worker): Rewrite to use siginfo_t second argument. (kill_pgrp): Ditto. (kill0): Define new function pulled from kill(). (kill): Rewrite as frontend to kill0. (killsys): Define new function. * sigproc.cc (sigelem): Eliminate. (sigpacket): Move to sigproc.h. Subsume sigelem. (pending_signals): Use sigpacket rather than sigelem for everything. (sig_clear): Ditto. (wait_sig): Ditto. (sig_send): Rewrite to use siginfo_t argument. (sig_send): New function wratpper to sig_send with siginfo_t argument. (wait_subproc): Accommodate siginfo_t considerations. * thread.cc (pthread_kill): Ditto. * sigproc.h (sigpacket): Move here. (sigpacket::process): Declare "new" function. (sig_handle): Eliminate declaration. (sig_send): Declare with new paramaters. (killsys): Declare new function. (kill_pgrp): Declare. * winsup.h: Move some signal-specific stuff to sigproc.h. * include/cygwin/signal.h: Tweak some siginfo_t stuff.
